Shellac
Shellac is a natural resin secreted by the lac insect, primarily found in South Asia. It is processed into flakes or powder form and dissolved in alcohol to create a versatile film-forming agent. Shellac provides excellent adhesion, gloss, and moisture resistance, making it widely used as a wood finish, food glaze, and pharmaceutical coating. It is valued for its natural origin, biodegradability, and safe use in food and cosmetic applications.
